damnit! they are going on their 4th week and have started yellowing. growing in peat moss. at first i thought it was nitrogen defiency so i added 20-20-20 diluted at 1/4 strength for the first time a few days ago. but it hasnt helped! my last resort is epsom salt but i dont want to add it if i dont have to. if i do have to add it should i spray or water? can someone plz get back at me asap? more info in my grow journal if needed.
that yellowing looks like nitrogen def to me for sure... i would continue to feed the grow nutes and steadily increase them as the grow progresses... good luck and looking good so far.
nitrogen if they havent responded to your ferts it maybe locked out, whats your PH,........ water & runoff
around 6.5. ive added 20-20-20 half strenght and foliar sprayed them with epsom salt. hard to tell if it helped...the leaves affected wont recover right? so i have to keep an eye on the new growth then.
You might consider moving them out of those tiny ass pots into something that they can spread out in.
